What is the difference between GitOps and CI/CD?

CI/CD is the broad umbrella for continuous integration and continuous delivery or deployment, covering everything from building code to releasing it to production. GitOps is a specific pattern for the CD side, in which the desired state of infrastructure and applications is stored in Git and a controller continuously reconciles the running environment to match. All GitOps is a form of CD; not all CD is GitOps.

Definitions

CI/CD covers two related practices. Continuous integration is the discipline of merging code frequently, running automated tests on every change, and producing a deployable artefact. Continuous delivery extends this by ensuring every successful build is releasable to production with a click. Continuous deployment goes one step further and ships every successful build to production automatically.

GitOps, formalised by the OpenGitOps project under the CNCF, is a delivery methodology with four principles: configuration must be declarative, the desired state must be versioned and immutable in Git, software agents must pull and apply that state automatically, and agents must continuously detect and correct drift. See what GitOps is for more detail.

GitOps and CI/CD side by side

The relationship between them

CI/CD describes the goal: changes flow from a developer's commit to a running production environment quickly, safely, and repeatedly. GitOps describes one way of achieving the CD portion of that goal: by treating Git as the single source of truth and a controller as the actuator that reconciles reality to that truth.

A typical modern pipeline keeps both:

1. Continuous integration runs on every pull request: tests, security scans, image builds.
2. On merge to the main branch, the CI system pushes a new container image to a registry and updates a manifest in a Git repository to reference the new tag.
3. A GitOps controller (Argo CD or Flux) sees the change, syncs it to the cluster, and reports status back.
4. If anyone changes the cluster directly, the controller detects the drift and reverts it.

This split keeps the strengths of both: a flexible CI engine for builds and tests, and a deterministic CD layer for deployments.

When CI/CD without GitOps is the right choice

• Your targets are not Kubernetes-centric: serverless functions, mainframes, virtual machines with imperative configuration.
• Your deployment logic is heavily procedural and does not map cleanly to declarative manifests.
• Your team has deep investment in push-based pipelines and the cost of introducing a GitOps controller outweighs the benefit.
• You are early in your platform journey and adding GitOps now would slow more important work.

When to adopt GitOps as your CD layer

• You run Kubernetes at scale and want every cluster's state to be reproducible from Git.
• You need a strong audit trail where every change is a pull request and every revert is a commit.
• You operate across multiple regions or clusters and want a single declarative model.
• You want continuous drift correction so manual changes do not silently persist.
• Your security posture benefits from clusters pulling state rather than CI systems holding production credentials.

Common misconceptions

• GitOps replaces CI. It does not. Code still has to compile, tests still have to run, images still have to be built. GitOps handles deployment, not build.
• If you use Git in your pipeline, you are doing GitOps. Storing pipeline scripts in Git is good practice but not GitOps. GitOps requires declarative state, pull-based reconciliation, and continuous drift correction.
• GitOps is only for Kubernetes. The most mature tooling targets Kubernetes, but the principles apply to any declarative platform, including Terraform via tools such as Atlantis.

Frequently Asked Questions

Is GitOps better than CI/CD?

The comparison is not direct. GitOps is a way of doing CD, so the right question is whether GitOps is a better CD model than push-based deployments for your workloads. For Kubernetes at scale, the answer is often yes. For other targets, traditional CI/CD pipelines may still be the better fit.

Can we do GitOps with GitHub Actions or GitLab CI?

Yes for the CI portion. For the CD portion you typically pair these with a controller such as Argo CD or Flux. GitHub Actions can update a manifest repository, and the GitOps controller picks up the change and reconciles the cluster.

What is pull-based deployment?

In pull-based deployment a controller running inside the target environment fetches the desired state from a Git repository and applies it. This contrasts with push-based deployment, where an external CI server connects into the environment to apply changes. Pull-based deployment improves security because clusters do not expose deployment credentials to external systems.

Does GitOps work for databases and stateful services?GitOps handles the declarative parts well: operator manifests, schema definitions, configuration. Stateful migrations and data operations usually require additional tooling and care, regardless of whether you use GitOps or a traditional CD pipeline.

How do we start with GitOps?

Pick a single non-critical application running on Kubernetes. Move its deployment manifests into a separate Git repository, install Argo CD or Flux, point it at the repository, and let it reconcile. Once the team is comfortable, expand to other applications and add policies, secrets management, and progressive delivery.
